About

This study is designed to evaluate the effects of daily sweet cherry consumption on markers of metabolic health in adults. Cherries are rich in bioactive compounds, such as anthocyanins and phenolic acids, which may help reduce oxidative stress, inflammation, and early risk factors for conditions like type 2 diabetes and cardiovascular disease. Participants will consume 280 grams of fresh sweet cherries every day for 42 consecutive days. Blood and urine samples will be collected at four time points: before the intervention (baseline), at day 21, at day 42 (end of the intervention), and two weeks after stopping cherry consumption.

The study will measure changes in blood sugar regulation, markers of inflammation, oxidative stress, liver and kidney function, and immune response. Waist circumference and body mass index will also be recorded.

The aim of this study is to test whether daily cherry consumption can support metabolic health in healthy adults and to provide data that may inform larger and longer clinical trials in the future.
